UNAUTHORIZED DEBIT ORDER AND CANCELLATION FAILURE

I have emailed The Unlimited a few times now, and called. I never gave anyone permission to debit my account monthly. I also cannot cancel this policy. No one has returned to me via email. When Customer care calls I get sent around to different people, but the result is the same. I want my policy cancelled and the debit order removed.<br> <br> I see constant complaints about this company yet you still go on!
